GLOTH=PRESSING MACHINE.

SPECIFICATION forming part of Letters Patent No. 387,288, dated August 7, 1888.

Application filed Dccrmber 2'7, 1887. Serial No. 258,998. (No model.)

'Serial No. 212,702, I have described a machine for pressing cloth, and it will beunderstood that the parts which are the subject of this application may be used in that machine, and the pressing appliances will be operated by mechanism similar to that therein described.

In the drawings, Figure 1 is a sectional view through the cylinders, rolls, apron, steamer, and bed-plates. Figs. 2 and'S are detail views showing the arrangements for the support of the apron. Fig. at shows a modification.

a and a are two pressing-cylinders,each provided with an internal steamchamber for heating it.

I) b are two bed-plates which press the cloth against the cylinder a. These bed-plates are also chambered, so as to be heated by steam.

b is a bed-plate arranged below the cylinder (0', to press the cloth against said cylinder. This bed-plate is also chambered, so as to be heated by steam. In use the surfaces of these cylinders and bed-plates are dry, so that the pressure exerted by them is a dry pressure.

at is an apron, preferably of felt, which runs upon the rollers e 6 6 These rollers are journaled at the extremities of the armsfff of a frame (one for each end of the rollers) which is mounted upon a central shaft, g.

The arm f is provided with means of adjustment, whereby it may be lengthened or shortened, so as to increase or diminish the tension upon the apron d. This adjustment is shown in Fig. 8 as a set-screw and slot.

0 is a steamer, which is arranged to moisten the apron at just before it comes in contact with the cloth being pressed.

his a stretcher-roll of ordinary construction.

It will be understood that the various bedplates are provided with journals,as described in my said former application, and that the said journals and the journal of the shaft gare all mounted in suitable supports whereby each may be moved to and from its pressingcylinder, so as to press or release pressure as required.

The cloth enters in the direction of the arrow Fi 1 )asses successivel under the pressure of the bed-plates b b, thence over the stretcher-roll 71, whereby its proper .width is maintained, thence between the cylinder a and bed-plate b and thence around the cylinder aand betweenitand the moistened apron (I. Rollers e c and the tension of the apron between them will create a pressure upon the cloth between the apron and the bedplate a, and, if desired, the rollers c 6' may be hollow and heated by steam. If it is desired to increase the pressure between the apron and the cylinder a, an additional bed-plate, if, maybe used, as shown in dotted lines in Fig. 1.

Sometimes it may be thought desirable to omit the bed-plate b, and in such case the cloth may be conducted directly from the cylinder a, in the course of the dotted line t, to the point at which it enters between the cylinder a and the apron d.

I do not confine myself to the details of construction nor to the presence of all of the elements or mechanisms described, as I am aware that the construction may be varied in certain portions of the apparatus, and some elements may be used without others while still obtain ing the benefit of my invention to a greater or less extent.

Instead of steamer 0, (shown in Fig. 1,) I may employ an equivalent, as the device shown in Fig. 4., where the apron cl is moistened by the cloth-covered roller j, which in turn is moistened by being partly submerged in hot or boiling water contained in a trough, k. The roller Z acts as a squeezer to prevent the cloth on roller j from being too wet, as in a sizing apparatus.

I claim- 1. In a cloth-pressing machine, a dry press ing-surface provided with a heating-chamber, and an apron arranged successively along the path in which the cloth travels,means whereby the cloth is pressed against said pressing-surface and said apron, and means for nioistening said apron, substantially as described.

2. In combination, the cylinder, a pressingsurface, an apron, means whereby the apron is pressed upon the cloth between it and the cylinder, and means whereby the apron is moistened, substantially as described.

3. In combination, a cylinder, a press plate, a moisture-absorbing apron, a steamer for moistening said apron, and mechanism whereby said apron is pressed in contact with the cloth against the cylinder,whereby the cloth, after receiving pressure from the press-plate, is again pressed in contact with the moistened apron, substantially as described.

4. In combination, the cylinder and apron, means whereby the apron is pressed upon the cloth between it and the cylinder, and a steamer or moistener arranged to deposit moisture on the face of the apron which comes next the cloth, substantially as described.

5. In combination, a cylinder, an endless apron, the rollers e e 6 supporting saidapron, arms f f f, and a central shaft, 9, substantially as described.

6. In combination, two cylinders, one or more bed-plates arranged to press the cloth against one of said cylinders, and the endless apron arranged to press the cloth against the other of said cylinders, and means whereby the apron is pressed upon the cloth, and the steamer arranged to deposit moisture upon the said apron, substantially as described.

7. In combination, the cylinder a, one or more bed-plates operating therewith, the cylinder a, the bed-plate b", the endless apron d, and means for supporting said apron, substantially as described.
